Abstract
There are definite relations among growth of plants and function of roots and shoots. Interactions between shoot and roots can also be characterized and quantified by allometric relationships. In order to study the effect of phosphate solubilizing bacteria and other phosphate fertilizers effects on allometeic relationship for root and shoot of rice, an experiment was conducted in randomized complete block design with three replications. The filed experiment was conducted at the Rice Research Institute located in Tonekabon- Iran. Fertilizer treatments included microbial biophosphate, phosphate solubilizing bacteria (PSB), rock phosphate (A), triple super phosphate (TSP), triple superphosphate %50 (TSP50%), triplesuper phosphate%50 + PSB and rock phosphate + PSB. Root and shoot characteristics including root dry weight (RDW), leaf dry weight (LDW), shoot dry weight (SDW), total dry weight (TDW) and rate of root/shoot were determined. Analysis of variance showed that the effect of different treatments on the allometric coefficient was significant (P<0.05). Shoot dry weight and total dry weight were the highest in A + PSB treatment. The highest rate of RDW and rate of root/shoot were obtained in A+PSB treatment while the highest LDW was observed in TSP50% treatment. Allometric coefficient was the highest in A+ PSB treatment.
